I'm experimenting with jj this weekend. It seems pretty nice so far, but the mental model is pretty different from git. For example, there's no `checkout` command. You do `jj new ABC` to switch to a commit, which creates a new empty commit on top of ABC.

Overall it seems like the Rust for Linux is making huge strides. Greg KH is super supportive of it[1] and the wider Linux community is pretty positive[2] (see all the quotes at the end of the slides). 1: https://lore.kernel.org/rust-for-linux/2025021954-flaccid-pucker-f7d9@gregkh/ 2: https://fosdem.org/2025/schedule/event/fosdem-2025-6507-rust-for-linux/

ASTs typically discard comments, and that's usually what you want. The only time (AFAICS) that preserving comments is useful is for writing a code formatter. Could you write a formatter in terms of a list of lexemes? A CST is a non-trivial bit of code for one use case.
